Types of Transducers for Trolling motor

There are basically three types of transducers that you can install on your trolling motor.

1. Transom mount Transducer – Also known as skimmer transducers are a common instrument used for fish finders to provide the exact underwater temperature. Transducer wires are wired to the transducer, and the end holding a screw to the connector that makes the installation easy and straightforward.

2. Side Imaging Transducer – A great choice for anglers as it can locate fish very quickly as it can see to the side of the boat. This transducer can send a signal on both sides, including downwards to ensure no obstacles between these signals.

3. Thru-Hull Transducer – As the name suggests, the transducer passes the signals through the hull as it’s mounted against the hull in the boat. It keeps your device safe from hitting the bottom as it is protected inside the hull.

Mounting a transducer on the trolling motor

Follow the given steps to install a transducer on your trolling motor.

Step 1 – Slide the strengthener (transom bracket) into the transducer (adapter) that you will find in your transducer kit and add the two washers on the left and right sides of the adapter.

Step 2 – Take two bolts and tighten each side of the washer until you get the angle you want.

Step 3 – Slot the hose clamp through the port around the transducer bracket, ensuring your transducer points straight down without tilting.

Step 4 – Secure the cables from the transducer along the shaft length of your trolling motor and ensure the cable is out of the way of the trolling motor propeller.

Tips on the mounting transducer to your trolling motor

Follow the below tips while you install a transducer to your trolling motor.

  • The transducer should be in contact with water all the time and not moving up and down the water.
  • The location of the transom should be in a direction where there are no obstructions on either side.
  • Your transducer should be mounted as close to the centerline of the boat or the engine.
  • While mounting the transducer, it should not touch the shaft else; it would scratch the surface of the motor.
  • Adjust the angle of the transducer as it needs to sit as close to the level as possible.

How To Mount A Transducer On A Minn Kota Trolling Motor?

Are you looking for tips to install a transducer on your Minn Kota trolling motor on your own? Well, let me help you out with some handy tips and tricks.

First of all, the Minn Kota Trolling Motor has a bracket on the top made up of aluminum. They extend all the way to the bottom end of the trolling motor, where you will see a hose. It’s a coiled-shaped hose, which is of great advantage as you can easily roll your cables or zip ties on it.

Things needed to mount a transducer on a Minn Kota trolling motor

  • Transducer
  • Transducer cords
  • Heavy cables
  • Heavy-duty zip lines

Steps to mount a transducer to the Minn Kota trolling motor

  • First, you need to tighten the metal along with the bracket and then start rolling your cables. You can also use heavy-duty zip lines instead of cables.
  • Next, you need to remove the head of the trolling motor and locate the shaft.
  • Once you’ve secured the shaft, take it out and fold it.
  • When the shaft is taken out, you will find a flat spot on it. Through this spot, you should run the transducer cords to mount in on the trolling motor.
    • After this, you can finally secure the zip ties at the bottom end.

When attaching the transducer cord, make sure that you only use waterproof silicone and ensure that they are secure and tight with the help of zip ties. This should also be let out to dry in the sun or cool temperatures. If you don’t let it dry, then goop will form on the main place where the trolling motor operates, and this will be a much difficult task for you. Once the goop and everything else is dried and settled, your transducer is ready on your Minn Kota trolling motor.
